“Just got a call from Mindy McCready's best friend that she shot and killed herself this evening. My heart breaks for her two boys. RIP,” Andrea Canning, a reporter for NBC's "Dateline," tweeted late Sunday. Canning later tweeted that police had yet to confirm whether McCready’s death was a suicide.

McCready's 1996 debut album, “Ten Thousand Angels,” went multi-platinum, and two songs off the record, the title cut and "Guys Do It All the Time," were No. 1 country hits. Four other studio albums followed.

In the last decade, however, McCready's music took a back seat to her often-troubled personal life, which included a number of legal problems and the revelation of a long-running affair with married former New York Yankees pitcher Roger Clemens.

The last few months of McCready's life were a series of tabloid headlines.

In January, the singer’s boyfriend, David Wilson, was found dead of an apparent self-inflicted gunshot wound. But questions surrounding the circumstances of the shooting led authorities to keep his death under investigation.

In an interview with "Dateline" in late January, McCready denied any involvement in her live-in boyfriend's death after Canning asked her whether she had shot him.

"Oh my God, no. Oh my God, no," she responded. "He was my life. We were each other's life. There's no way to tell where one of us began and the other ended. We slept together every night holding hands."

After Wilson’s death, the singer -- who had struggled with alcohol and mental health issues -- checked herself into an inpatient rehab facility for treatment. Her two sons -- Wilson was the father of her youngest child -- were removed from her care.

Country music singer Mindy McCready has died, police say. The 37-year-old singer was found dead Sunday night in Heber Springs, Ark., according to reports. The Cleburne County Sheriff's Office confirmed the singer's death. Read story
